Network Simulation

The ALLEGRA 56 adapter card  provides the user with the ability to simulate the Frame Relay network.  This enables point-to-point communication between Frame Relay devices without attaching to a real Frame Relay cloud.  Note: Auto Detection of management type is not supported when Network Simulation is enabled.


IO Base Address

The IO Base Address is the port address of the ALLEGRA 56 adapter card. The ALLEGRA 56 address is set by the user during adapter installation. This address must correspond with the switch settings on the adapter card.


Interrupt

The ALLEGRA 56 card generates a hardware interrupt to indicate various conditions to the CPU. The ALLEGRA 56 interrupt number is set by the user during adapter installation. The ALLEGRA 56 card supports interrupt numbers:  5,9, 10, 11, 12, & 15.This address must correspond with the switch settings on the adapter card.


DMA Channel

The ALLEGRA 56 card uses one Direct Memory Access (DMA) channel to act as a bus master device. The ALLEGRA 56 DMA Channel is set by the user during adapter installation. The ALLEGRA 56 card supports DMA channels: 0,1,3,5, 6, & 7. This address must correspond with the switch settings on the adapter card.


RFC-1490 Encapsulation

RFC-1490 is the standard that allows equipment from different vendors to exchange messages over Frame Relay. Before it was defined, vendors would use proprietary schemes that allowed communication between equipment from the same vendor, but not equipment from different vendors.  RFC-1490 enables communications between any vendor that supports the RFC-1490 standard.

When the RFC-1490 parameter is enabled,  RFC-1490 encapsulation rules are applied to each message when this feature is enabled. To determine whether RFC-1490 encapsulation for the ALLEGRA 56 software you need to know what the remote device is on the other side of the Frame Relay network.

When RFC-1490 is not enabled, standard Frame Relay encapsulation (Q.922) is performed on the packet.


ARP Type

If the device connected to the other side of the Frame Relay network supports Frame Relay ARPs such as a Wellfleet Router, set this parameter to "ARP".

If the device connected to the other side of the Frame Relay network does NOT support Frame Relay ARPs such as a Cisco Router, set this parameter to "ICMP-Echo".

This parameter only applies if the RFC-1490 parameter has been enabled.


IP Message Encapsulation

If the device connected to the other side of the Frame Relay network routes IP packets, set this parameter to "ROUTED".

If the device connected to the other side of the Frame Relay network bridges IP packets or is a terminating workstation, set this parameter to "BRIDGED".

This parameter only applies if the RFC-1490 parameter has been enabled.


IPX Message Encapsulation

If the device connected to the other side of the Frame Relay network routes IPX packets, set this parameter to "ROUTED".

If the device connected to the other side of the Frame Relay network bridges IPX packets or is a terminating workstation, set this parameter to "BRIDGED".

This parameter only applies if the RFC-1490 parameter has been enabled.


Management Type

This parameter specifies the type of Frame Relay management message the ALLEGRA 56 adapter is to use.  There are two standards for Frame Relay: ANSI T1.617 Annex D and Local Management Interface (LMI).  The ALLEGRA 56 has the capability to automatically detect the management type in use by the Frame Relay switch  or if the management type is known by the user,  he/she can set this parameter to the appropriate type.


MAC Address

Because the ALLEGRA 56 emulates a LAN Adapter, a unique MAC Address is provided with each ALLEGRA 56 Adapter and has been programmed into the PROM at the factory.  This field allows the user to override the pre-programmed Address.  Only in rare occasions would the user want to change this value.  Note: Extreme caution MUST be taken to ensure uniqueness of this MAC Address.  Duplicate MAC Addresses can cause extreme agitation and affect operations.

To override the pre-programmed MAC Address, enter a 6 digit NON-ZERO value.  Entries in this field must be entered in HEX and delimited by the '-' character.  Setting the field to all zeros (00-00-00-00-00-00) indicates that the factory setting should be used.

Example: 00-20-69-11-ab-cd


Line Rate

This parameter specifies the line rate for the ALLEGRA 56 adapter to use. The ALLEGRA 56 adapter supports 56 kbps and 9.6 kbps rates.
